Specification of Letters Patent.

VApplication filed'DecemlxerZ, 1905. Serial No. 293,185.

To au whom it may concern:

Beit known that I, JULIUs H; SCHLAFLY, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Binding-Sheets for Concrete- Work and I do hereby declare that the following is a full, clear, and exact description of the same, "reference being had to the annexed drawings, making a part of this speciiication.

The object of the present invention is to provide a sheet of metal adapted to bind concrete-workin such a mannerthat after the concrete has changed from a plastic state to a'rigid or hardened condition the bindingsheet will be so connected that there can be no relative movement as between the conpart of this specification.

tact-surface of the binding-sheet and the concrete. This objectI accomplish by the peculiar construction of the bindin -sheet shown in the annexed drawings, ma g a Referring to the drawings, Figure lis a perspective view showing a ortion of my improved binding-sheet and ilustrating the sheet partly covered withconcrete-work. Fig. 2 is a view showing a portion `of the binding-sheet drawn upon a larger scale than that shown in Fig. 1. Fig. 3 is a view illustrating my improved binding-sheet located in cement-work and the cenent connected upon both faces of the binding-sheet. y

Similar numerals of reference indicate corresponding parts in all the .figures of the drawings.

In the accompanying drawings, 1 re resents the binding-sheet, which is formed) of metal and of any desired size -and thickness.

Inuse where it is desired to construct floors or other concrete-work of large areas a number of binding-sheets must necessarily be employed, which sheets are connected together as hereinafter described.

For the purpose of lroducing what might be termed an integra part or structure so far as the concrete-work within itself is concerned the binding-sheets are provided with roughened surfaces, which roughened surfaces may be of the form shown, and, as shown, the surface consists of corrugations; but the onlyobject designed to be accomplished is to provide a binding-,sheet having roughened surfaces of such a nature and kind that substantially and practically all of the surfaces of the inding-sheet present consus crete contact-faces, so that there can be no alternating grooves and ridges the concrete while in a plastic state can be located in and upon alternating grooves and ridges, thereby producing an alternating tongue-and groove embodiment of thebinding-sheet in the concrete-work, and by producingl roughened surfaces upon the entire surface' of the binding-sheet the entire surface of the concrete-Work will be in contact with the binding-sheet, by which arrangement no particular part or spot of the binding-sheet isy subjected to any overdue strain arising from any vibrations of the finished concretework. This feature is an important one, for the reason that the adhesiveness as between the binding-sheet and the concrete-work is v.uniform throughout the entire length and Abreadth of the concreteA regardless of size.

It is well 'understood that where plain contact-surfaces exist, as between the bindingsheets and the concrete-work, there is a tendency Ytoward relative movement as between metal and concrete faces, and of course the strain of the concrete-work upon the bindingsheet is shifted to a certain extent from the lain surfaces to the roughened surfaces, or,

in other words, the adhesiveness is not equal and alike at all points, and by reason of the different degrgesof adhesiveness at different poin'ts of the surface, as between the bindingsheet and the concrete-work, there is a tendency toward a slipping movement of the concrete-work upon the surface of the bindingsheet, thereby causing or producing greater Strain upon certain portions of the concretework than others, the resultand effect being toward producing breaks or a cracking of theconcrcte after it has become hardened; but by the use'of my improved binding-sheets there is and can be no difference in the degree of strain, or, Ain other words, there is and can be no shifting of the strain or the structures a series of sheets, such as 1, must bev employed, and when so employed the edges of the sheets can be hooked together, as bestillustrated in Fig. 3.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, iszl 1; A binding-sheet for concrete-Work provided with alternating dovetailed grooves and ridges and corrugations located transverse to the alternating grooves' and ridges, substantially as and for the purpose speci- 2. A binding-sheet for concrete-Work, provided With alternating ridges and grooves, the tops, bottoms, and side Wall-faces of said l alternating ridgesl and grooves provided With roughened surfaces, and the sheet provided with roughened surfaces, intermediate the ridges and grooves, said ridges and grooves located transverse to the roughened intermediate surfaces, substantially as and for the purpose specified.

3. As an improved article of manufacture, a binding-sheet provided with dovetailed grooves and ridges and the sheet corrugated transverse to the dovetailed grooves and ridges and the corrugartions extended throughout the Walls of the dovetailed ridges and grooves, substantially as and for the purpose specified. f

In testimony that I claim the" above I have hereunto subscribed my name in the presence of two Witnessest JULIUs H. soHLAFLY.
